Synthesis and Acid-Base Properties of Tetraphenylporphine Derivatives with Amino Acid "Anchor" Groups.

Asymmetrically substituted 5,10,15,20-tetraphenylporphyrin derivatives such as 5-(4-aminophenyl)10,15,20-triphenylporphine, 5-[4-(tyrosinylamino)phenyl]-10,15,20-triphenylporphine and 5-{4-[(--butoxycarbonyltyrosinyl)amino]phenyl}-10,15,20-triphenylporphine were synthesized. Their spectral and acid-base properties were studied. The acid-base interactions of the obtained compounds in the binary acetonitrile-perchloric acid and dimethyl sulfoxide-potassium cryptate (KOH[222]) systems were studied by spectrophotometry method.

Fluorescence properties and quantum-chemical modeling of tert-butyl-substituted porphyrazines: Structural and ionization effect.

Synthesis and identification of tetrakis-[5,6-bis(4-tert-butylphenyl)pyrazino] porphyrazine, tetra-(4-tert-butyl)phthalocyanine and octakis-(4-tert-butylphenyl)porphyrazine were carried out. Spectrophotometric method was used to study the spectral, acidic and fluorescence properties of the synthesized compounds. It was determined that the synthesized tert-butyl-substituted porphyrazines exhibit a high sensitivity of fluorescence to the molecule ionization.
